You can transfer files, videos, photos, images, documents, the clipboard and other content to another device

Make sure you enable the "Bluetooth clipboard transfer" and/or the "WiFi clipboard transfer" options in the app settings (View) - Clipboard section. Check that both devices are either using Bluetooth or the same WiFi network. Make sure that both devices have AltaMail installed and open.

Open the clipboard screen in the left side panel inside AltaMail. You should now see a list of devices in the bottom of the screen.

You can tap on a device to send the clipboard. You can also check one or more files and drag them to each device. Hint: tap and hold for a short time, before dragging.

When viewing files and other content, you can choose "Send to Device" from the action menu to send content to another device.
